What's a frugal tip that just drives you crazy because it doesn't work for you?

We all have our frugal ways but there's a standard list. Cutting eating out, shop smarter yadda yadda.

I hate the one where people say go outside for free exercise. Summers where I live hit 120° f. I'm not jogging in that. Our summers hospitalize and kill people every year.i work from home and already have a hard enough time establishing work/ home separation. I've tried and it seems a gym membership is my only option.

Whats yours?
